Application filed February 15, 1913.

fi o-612221071077), it m' 'ay concern Be it known that 1, ARTHUR W;WARNER,-

the following is a specification.

A prime object of my invention is to provide means for preventing theescape 'of-dust and ether fine particles, 'during the operastorage binto a hopper.

The present invention is particularly iapplicable for use in connectionwith charging apparatus employed in a gas 'retort house for chargingcoal into retorts, and in the embodiments as illustrated in the drawing,bin and the upper por ion of a coal hopper, the latter being carried ona charging machine designed to travel in front of a bench of retorts andunder the stationary storage bin.

In the accompanying drawing illustrating an application of my invention:Figure 1 is a vertical sectional 'view of a portion of acoal bin and aportion of the upper end of a coal hopper designed to be carried on. thecharging apparatus; Fig. 2 is a detailed plan and sectional view, thesection being taken on line 11-11 ofFig. 1; Fig. 3 is an enlarged "sideelevational view particularly showing a guide rod and adjusting nuts;and Fig. 4 is a part horizontal sectional view and a part plan, thesection being taken on line IV- 'IV of Fig. 3 looking in the directionof the arrows.

Referring to the drawing, 1 designates a stationary bin having a slopingbottom and coal discharging openings controlledby doors or gates 3operatively connected with an operating rod 4, saidrod being designed tobe moved to open the door by any suitable means, not shown. Thestationary bin, as illustrated, is of rectangular shape, and isprovidcdwith depending side members 5, a depending rear member '6, and adepending front'member, not shown, corresponding with the said side. andrear depending members. The said members, when assembled and secured tothe bin, constitute Specification of Letters Patent.

from a 'provided ,with sleeves 12 2,the latter being Patented a nea,rats.

a rigid rectangular frame. Secured to the lower edges of the saidside,frontjand rear depending members, I provide strips or pieces 7 ofsome-suitable fiexiblemfaterial as strong canvas, the upper edge of saidstrips being held between the d wnwardly depending members arid bars 8,tlie'latter bei'n secured to the rigid frame by means of ts 9 passedthrough the bars 8 and the ripper lapped-over edges of "the flexiblepiece or pieces 7. l

to be secured to the respective side members 5 by bolts 11. Members 10are similar to the 'bra'clretmembets 21 (see Fig. 4) and are preferablyformed integral therewith into which guide rods 13 entered. For thepurpose of giving a slight play to the guide rods, the interior of thesleeves 12 are preferably beveled as par- 'ticularly hown at 14 in Fig.3. Guide rods 13 are designed to be moved vertically through the sleeves12, and the upper ends of said rods are screw threaded and provided withadjusting nuts 15 and 16.

17 designates a rigid metallic frame of rectangular shape comprisinginner bars 18 and an outer flanged member or members 19. This frame isattached to the lower edges of the flexible strips or pieces 7 by havingthe overlapped edges thereof entered be tween the inner and outermembers 18,and

10 designates metallic members adapted I respective sleeves 12 ofmembers 10, I provide bracket member-s21 each formed with an internallythreaded collar portion 22 into which the lower ends of the respectiveguide rods are adapted to be screwed. As particularly shown by Fig. 3,the lower ends of the guide rods 13, in addition to being threaded,

are each provided with a bolt opening 23,

tvhich opening registers with a horizontally and bolt passed through thesleeve, guide rod, and the lower rigid frame.

extending bolt opening 2% in the sleeve, 25 designates a describedconstitute simple The means just depending from and efficient closuremeans the storage bin and adapted to coeperate with the hopper or otherreceptacle into which the material contained-in the bin is to beintroduced.

The coal hopper or other receptacle de- 5 signed to receive coal orother material. from the discharge opening of the stationary bin isindicated by 26, and as above stated, this hopper 26 is designed to becarried on the upper portion of a charging apparatus not shown. Thehopper or the opening through which the material is introduced to thehopper is of rectangular shape and is bounded by a mouthpiece 27. Thismouth-piece 27 is designed to make contact with the closure means or thelower-metallic frame thereof,

as the charging apparatus carrying the hopper is moved under the bin..As will be seen, the flanged portions 19 and the mouth-piece 27 arecomplementally 20 formed soas to provide for an automatic raising of theframe l7.by the positioning of the hopper below'the discharge openings,

the nuts 15 and-16 being adjustedso as to 1 cause said frame to haveitslower position at a point where the coacting faces of these.

flanged portions will provide a proper meeting without damaging eitherframe or hoppe r,the movement of the hopper to position j-moving theframe vertically, the rods 13 moving upwardly, as shown in Fig. 1, and

thus causing said frame 17 to act somewhat as afloating frame. When thehopper passes .out of engagement with the frame, the lat ter returns toits lower position, the nuts 15 acting, to limit the length of suchreturn movement. -lFromfthe. construction described, it will be notedthat l have provided simple and efiif:;eient -;,means -for preventin theescape of 40 iidiisaetc, into the building m which the ap- :paratusis-located during the operation of transferring the coal, etc., from thestationary bin to the movable hopper.

-.-%What- I claim is 1. In combination, a bin having a dischargeopening, a hopper positionable below said opening, and means carried bythe bin for closing the space between the bin and hopper against escapeof dust, etc.,' said means including a frame movable vertically iinionedirection by the positioning of the hopper below the opening.

' 2.; In combination, a bin having a dis charge opening, a hopperpositionable below saidopening, and means carried by the bin for closingthe spacebetween the bin and hopper against escape of dust, etc., saidmeansincluding a frame movable vertically in one direction bythepositioning of the hopper below the opening, said discharge openingbeing positionedpermanently above the top plane of the hopper.

3. In combination, a bin having a dis- .charge opening, a hopperpositionable below said opening, and means carried by the bin forclosing the space between the bin and hopper against escape of dust,etc., said means including a frame movable vertically in one directionby the positioning of the hopperbelow the opening, said'means extendingpermanently below the plane of the discharge opening.
